GE TEY3100 Molded Case Circuit Breaker 100A 3 Pole 277/480V AC

SKU CH-JA3N-0JGTH

A 100 A, three-pole molded-case breaker rated 277/480 V AC with a 14 kA interrupting capacity for GE AE lighting panels

  • Reliable three-phase protection for 277/480 V AC systems
  • 14 kA interrupting capacity clears high fault currents safely
  • Thermal-magnetic trip responds to both overload and short-circuit events
  • 100 A rating in a 125 A frame fits standard GE AE lighting panels
  • Bolt-on mounting and lug terminals simplify panelboard installation

Circuit Breaker for Three-Phase Panels

The GE TEY3100 is a molded-case circuit breaker rated at 100 amps for three-phase 277/480V AC systems. It uses a thermal-magnetic trip mechanism with a fixed instantaneous setting and a high amp trip point of 200 amps. The unit carries a 14kA interrupting rating at its rated voltage.

Bolt-On Mounting for GE AE Panels

This breaker mounts directly onto compatible GE AE lighting panelboards using a bolt-on connection. It occupies a standard three-pole footprint within a 125A frame size and terminates conductors with lug terminals. The ABC phase connection suits typical panel layouts.

Thermal-Magnetic Protection in a Compact Frame

Thermal-magnetic operation provides overload and short-circuit protection without external control power. The fixed instantaneous trip responds quickly to fault currents up to the 14kA rating. Physical dimensions are 5.25 inches high, 3 inches wide and 3.06 inches deep.

Questions about this item

Will the 14 kA interrupting rating at 277/480 V AC be enough for my panel's available fault current?

The breaker is rated to interrupt up to 14 kA at 277/480 V AC; confirm your panel's available fault current does not exceed this value before installation.

How much heat does the 100 A thermal-magnetic trip unit produce during continuous all-day operation?

Normal operation at 100 A generates warmth typical for a 125 A frame thermal-magnetic breaker; ensure the enclosure ventilation meets GE's installation guidelines.

Does the bolt-on mounting require a GE AE lighting panel with a 125 A TEY frame bus?

Yes, the breaker is designed for bolt-on mounting in GE AE lighting panels that accept a 125 A TEY frame.
